Death Stranding has 56 Memory Chip Locations (Collectibles). Finding all of them unlocks the trophy Fount of Knowledge & A Thirst for Knowledge. Memory Chip #31 is also required for a fabrication plan (trophy "Homo Faber").

None of the Memory Chips are missable! You can find all of them after the story in free-roam. You can see which collectibles have been found and which are missing by pressing Options-Button > Left > Data > Memory Chips. If you found it, it will have a key icon on it. You still need to decrypt the chips by bringing them to a terminal! Only after decrypting them at a terminal the trophy will unlock!

Before you start collecting the Chips here are a few important things to know:

Finish the Story first and build out a zipline network as soon as you unlock PCC Lvl. 2. The ziplines make it quick to reach any place.

Level up all facilities to 5 Stars (trophy "Best Beloved"). Make sure you sleep in a private room after you leveled up all facilities and read through all of their emails! Leveling up facilities grants you new emails (after sleeping to pass time). Reading those emails makes some specific Collectibles spawn on the map! You can't find some collectibles without leveling up their respective facilities first (pointed out in the text guide and video guide below).
If you find a chip during the story or while leveling facilities go ahead and pick it up. This will save you some backtracking later.
